Mercury 50 HP 4cyl - Year ?

[Riaant]

New Boat owner with Merc 50HP , 4 cyl. Would like to buy an owners manual, but not sure what year. Ser no: 9338307.<br /><br />My other problem, Enjin starts fine, run warm before pussing full throttle but then power dies. Keeping it full throttle for +/- 2 minutes the power wil just come back. Cleaned the carbs, replaced the plugs before this problem started. Any ideas... could it be the new plugs not breaking up when its cold???<br /><br />Any help - will be greatful.<br /><br />Thanks

Hi Riaant,<br />It is a 1986 unless it's a classic 50 then its an 87.<br />If it is fireing on all cyls' then the carb are set to lean. Otherwise the switch box could be bad pull off a plug wire while its running and see if thr RPMs drop,if so then that cyl is ok try another. If RPM doesn't drop then the problem is in the ing sys on that cylinder.<br />Do you need a service manual or a n owners manual?<br />...have fun...corm
